MEANS FOR ATTACI-IING PNEUMATIC TIRES.

Applidation filed August 23,

To all whom it may concern:

Be it known that 1, Aims C. MrLLnR, a citizen of the United States, residing atChicago, Illinois, have invented a new and useful Improvement in Means for Attaching Pneumatic Tires, of which thefollowing is a specification. Y

My invention has for itsobject to providea. simple means for and an expeditious mode of attaching "pneumatic tires of the single tnbetype or of the'inner tube type, tothe My invention relates more particularly to a simple means whereby a flat metallic rim affording a tire seat is employed in conjunction with a rubber tire having lateral integral flaps or flanges extending from its base,- and. contractible retaining bands for clamping said flanges to the metallic rim and thereby securing the tire against displacement My invention is illustrated in the accompanying drawings, inwhich Figure 1 is aside elevation of a wheel with the tire applied; Fig. 2 is a similar view of a section ofv the wheel rim enlarged, and Figs. 3 and 4 are cross-sectional views showing the tire deflated and inflatedfrespectively';

In the drawings, 1 represents the wooden felly or wheel rim, and 2 the metal rimlor tire.

3 represents the outer tube of thepneumatic tire, and 4 designates the usual inflatable tube such as is commonly employed in tires of this character. The base 5 of said outer tube is longitudinally severed, and said base portions are provided with the laterally extending integral flaps or flanges 6.

7 represents metallic clamping or retaining bands, which may be of any desired crosssection, although desirably oval. The outer surface of the metal rim 2 is inwardly beveled from its outer edges substantially 'to a line coincident with the inner sides of the retaining bands '7, thus affording the inclined. seats-8 for-the flanges 6 and the substantially horizontal seat 9 for the base 5.

It will be understood that-the retaining for contracting them, such as the provision of threaded lugs 10 and aturn buckle-0n drawing, Fig. 2. By these means, and assuming the tire-3 eitherwith or .without the inner tube 4 to have been placed u onthe metallic rim by slipping it sidewiset ereon, and the retaining bands 7 to be seated on the Specification of Letters Patent.

upper concave or inwardly inclined seats on the upper sides of the flanges 6, said bands 7 will be contracted or shortened in length by f manipulating the screwor other means pro- ,vided for that purpose until the. flanges 6 will be depressed upon the beveled seats 8 thereby carrying the base" 5 into firm con tact with its seat 9 and thus effecting aolamp length ing of the tire base throughout its firmly upon and within the seat oftlie-tire rim, Theefl'ect is that the tire is as securely held as though its base were confined between marginal upstanding flanges on the ere were mechanical con nection or interlocking between the retain: ing bands-and the metal rim, an( l'thereby all .of the advantages resulting from the absence .of these flanges, viz., greater facility of application and removal of the tire, as well as s1mplicity of construction and economy ofniaterial, are attained.

It will be-seen that with this construction theretainin g'band acts not only to exert vertical clamping strain upon'the tire flanges,

but that .by reason of the beveled seats said bands exert a lateral compression upon said base, tending -to force the parts thereof toward each other, thereby preventing their separation to such extent as to cause loss'of air, if the tire beused as-asingle tube, or the inching of the inner tube if such be used. t will be noted also that by the means above described the greatest compression upon the edges of the divided base is effected near its inner surface, and not only is this inward compression better effected byreason of the formation of the inclined seats in the outer surface of the flange, 6, but the'em-.

ployment of said seats effectually prevents the lateral displacement of the retaining bands themselves, and since ,the margins of the flanges 6 arethicker than the body of said flanges beneath the retaining bands, and the flanges 6 are deflected when clamped to conform to the inclination of the inclined seats8, said fiangeswillnot be withdrawn from beneath the retaining bands by lateral strain upon the tire.

, Vhile the combined downward and vertical pressure exerted by the bands upon, the base of the tire and thepeculiar. conformation of the tire seat will be sufficient, under ordinary conditions, to prevent lateral displacement of the tire, I may provide as an addi tional means 'for reventing su-ch displacement circumferential ribs or beads 7 which may be easily provided in the rolling of the clamp thebase'and flanges to their respeemetal rim, and these beads may be caused to engage grooves, 5 in the base ol the tire.

lt will hejobvious that my invention allords not only an economical means and a facile mode ol' applying and removing the. tires, but that they efl'ectually prevent creeping of the tires and that without injury to the flaps or flangesl urthermore, the thickness of the base of thc'tire and the shape of the retaining seats and of the retaining bands enables the tire to be used temporarily in a deflated condition, for it will be observed that the tread portion ol the tire when dellated will rest upon the inner surface ol the base ol the tire, while the sides will be doubled upon and overlie .the rounded surl'aces ol' the retainingbands? withoutinjury to the tire.

\Vhilel have described the. preferred lorms ol construction; it is obvious that my invention is not necessarily limited in its broader aspects to said structural details 1. The herein describedmeans for-securing apneumatic tire to a vehicle wheel, comprising a metallic wheel rim havinga circumferentially depressed tire seat centrally located, andmarginal inclined or beveled seats .in combination with a pneumatic tire having a base portion adapted to said central seat and lateral flanges adapted to said inclined seats, and contracti'ble retaining bands seated upon said flanges andadapted to tive seats, substantially as described.

2. 'lhc 'hcrein described means for securing a'1n1cumatic tire to a vehicle, wheel, comprising a metallic wheel rim having a centrally located depressed tire seat in its outer Slll'liltit,ttll(l radially,inclined seats extending from the tireseat toward the n'iarginsot the rim in combinationwith a tire having a relatively thick base portion adapted to the central seat, and lateral integral flanges adapted to said inclined seats, the outer surfaces of said flanges being provided also with seats and contractible retaining, bands applied thereto, substantiallyas described.

3! The herein described means for securing apnenmatic tire to a vehicle Wheel. comprising a metallic riln having a circumferentially depressed the seat provided with an upstanding head, in combination with a tire having a relatively thick base adapted to said seat and provided with a groove to receive saidbead and with transversely ta ered lateral flanges on either side of said ase, said flanges beingvthickest at their outer margins, and contractiblc retaining bands seated upon said flanges and adapted to clamp the tire toits seat, substantially as described.
